At 16Ω and 98dB/mW, these are super easy to drive, literally any device can drive them very loud, even ones that output only 5mW. A ver, voy a ser claro en este punto, ya tocará a los que les encantan las pruebas especificas con medidores de frecuencias o cualquier otra herramienta. The impulse response is able to show visually only the same or different polarity of the drivers and possible high-frequency resonance. I have gone through a variety of headphones over the years. I have accepted the minor flaws in a variety of very good headphones for the purposes of gaming, mobile music listening, etc.... but my go to was always my old Sony MDR7506. And I have been reluctant to get another pair of MDR7506's because of the one structural flaw in its design... the ultra heavy duty, and heavy weighted wire that inevitably loosens its connectivity at the point directly inside the headphone.

Meanwhile, the Sony offers a similar level of emphasis, but comes across as sounding brighter. This brightness, combined with the intense, dark lows, gives way to a fun and emotive sound that doesn’t skimp out on energy, either. Comparándolos con unos Meze 99 Classics, los Meze suenan un poco mejor (no por mucho) su desventaja es que debido a su diseño, también te obliga a escucharlos en casa, ademas de que son más caros que los Sony. The frequency response of the headphones can be represented as the selected equalizer setting in the player, applicable to headphones with a flat sound. Subjective "flatness" is perceived differently from external conditions: the volume level of the external noise and noise isolation headphones. When connected to an amplifier, the frequency response can change .The screws are under the thin piece of damping material approximately in the circled location. Lift it up a bit and take the screws out. Just standard Phillips screws. Careful not to accidentally drop the screws into the driver. Comfort and weight are perhaps the biggest selling points of this headphone. Sure, those specs are impressive, but they only get more impressive when you actually hold this headphone in your hands and realize just how incredibly light it is. You could wear this baby all day and never feel a thing. And, while a level of midrange detail still presents itself on the Sony MDR-1AM2, those details seem overwhelmed by the powerful low end. For some genres, this won’t be as much of a problem – but it still prevents the Sony from sounding great with anything (unlike the MSR7B). Highs Soundstage on the Audio Technica ATH-MSR7B comes across as pretty impressive, with good space and depth. While it’s more spacious than the Sony, it doesn’t sound quite as deep.

Compared to the previous version the bass has been tamed significantly, but it's still way above what it should be. If you are after a specific type of sound or "soundstage" or whatever other buzzwords are popular with self professed Audiophiles, stay away from these unless you are serious about tweaking your EQ settings and being exposed to some hard truths. If you are one of these lazy "experts" that demnds more bass, or midrange, or sense of space or whatever... you're really just describing a closed range of frequency responses and effects that you prefer. The MDR1AM2 does not cater to you... they will expose the flaws in some of the music you like so much in terms of mixing and mastering that you thought were great with other headphones that "boosted" the bass/treble/etc.. Boosting = Fake/Inaccurate/Unbalanced sound. Vas a leer en algunas reseñas que en comparación con "x" o "y" audífonos le falta un poco de brillo a este sonido en especifico, así como también leerás que no se ponen de acuerdo en si suenan apagados y sin brillo o si son sibilantes y muy echados para adelante. A ver, estos agudos son los que necesito, me gustan mucho los agudos, no me interesan los sonidos apagados y sin brillo, y con esto tengo el brillo que quiero, y dependiendo del reproductor pueden ser aún más marcados y brillantes. En resumen y para que se entienda, si escuchas la grabación de un alfiler caer al piso lo vas a percibir de forma correcta, el brillo que necesita ese sonido, no va a sonar como que tiraste una corcholata o una goma de borrar. Y sí, pueden haber audífonos que tengan agudos más brillantes, pero no por eso mejores, sino que al gusto de las personas que priman el uso de este tipo de sonido pues serán mejores. Some non-sound related complaints: Isolation is ok at best, a fair bit of cable noise or microphonics, no hardshell carrying case (assuming for portable use), and no "home-use" cable nor a 6.3mm adapter.

The frequency response in RAA is obtained through the reproduction and analysis of a special noise signal with the subsequent generation of an impulse response. The frequency response plot is constructed from the spectrum of the impulse response.During the measurements, a special amplifier was used with zero total output impedance over the entire frequency range, which required no compensation for the amplitude response . The microphone is calibrated to 45 kHz with an appropriate frequency response correction. For how much bass it has, I'm actually surprised how low distorsion actually is, so it's a winner in this regard.

And that depth on the Sony MDR-1AM2 constitutes most of it’s soundstage. There’s a characteristic separation of vocals from surrounding instrumentation. However, the soundstage still seems a bit cramped for instruments. The result is a deeper but narrower listening experience. The frequency response in RAA is obtained through the reproduction and analysis of a special noise signal with the subsequent generation of an impulse response. Under the hood, the Audio Technica ATH-MSR7B utilizes a larger 45 mm driver. In contrast, the MDR-1AM2 sports a smaller driver measuring 40 mm. Both being relatively easy to drive, neither one requires amplification, though the MSR7B would benefit slightly more from some amplification.Now for the high range. This is mostly what makes the headphones sound clearer. When I have these on a lower volume I could fall asleep with these on. The high range on a lower volume the headphone has a warm sound signature but when I turn up the volume some of that treble range can break through but instead of being able to sleep with them on they act more excited like most other headphones but much more explosive bass with these. Obviously you should never use headphones on high volume it will seriously damage your hearing. A strong sense of soundstage results from equal parts placement and depth – and the 1AM2 handles both with aplomb. There’s a certain gusto to this soundstage, reaching into your ears and dragging your brain out into the music. You can feel instrumentation and vocals as they should be felt – which is rare for a headphone at this price point. Other Observations
